Here a bio-inspired haptic-temperature fusion spiking neuron based on a combination of piezoresistive sensor and VO2 volatile memristor is demonstrated. The thermal characteristics of VO2 memristor and mechanical sensory properties of the piezoresistive sensor are exploited and combined in the same component, enabling multimodal in-sensor computing. This could provide a promising approach towards e-skin, neurorobotics and human-machine interaction technologies.
